Power comes at a price, but the price is worth paying...

This addon adds more Taints to the game.

Taints are Inscriptions powered by corrupt forces. As such, they are arcane so Oozemancers and other Zigur Zealots need not apply.
They do not get egos for scaling, instead they scale on a new stat called Taintmarks.
Taintmarks are a measure of how tainted by corrupted forces you are.
Each Taintmark increases the power and duration of Taints by 20%, but decrease you luck by 1 and increase the cooldown on nature gifts by 1.
Taintmarks are gained in many ways:
Each inscribed Taint grants a Taintmark.
Possessing a corrupt power source like Vim or Hate grants a Taintmark.
Being Undead, becoming Undead or changing your shape grants a Taintmark.
Giving in to your Hate grants a Taintmark.
Having Dark Ritual, Ruin or Blurred Mortality grant a Taintmark.
Having Blighted Summoning, Corrupted Shell, Bloodspring or Legacy of the Naloren grant a Taintmark.

Taintmarks are listed on your character sheet under stats.

Current Taints are only a little more rare than normal inscriptions. In v1 they will be much rarer but certain bosses will have a guaranteed Taint drop.

List of Taints:
Devourer: As before but also eats on of your own sustains for more healing.
Telepathy: As before but both effects have the same duration.
Darkness: Darkens the area, grants a temporary stealth boost and makes you activate stealth mode (even if you don't have it), but decreases your darkness resistance.
Vampire: Adds Life Leech chance and amount, but decreases your light resistance.
Blood Magic: Increases your Spellpower and lets you cast with life instead of mana/vim when needed, but decreases your physical save.
Reaper: Increases you physical power and restores resources on kills, but decreases your spell save.
Inversion: Grants damage affinity all, but changes some of your damage to healing.
Shade: Allows you to walk through walls and grants evasion, but reduces your healing.
Ghoulish Rot: Your hits apply Ghoulish Rot disease but your movement speed is decreased. Also blocks hits from being above a certain amount.
Banshee: Scream doing mind damage and causing confusion in nearby enemies, but silences you.
Bone Thorns: Sharp thorns sprout from your bones causing heavy bleeding damage to enemy attackers, but also causes you to bleed. Also increases armour and hardiness.
Blood Snare: Hurl a blood bomb at the target where it explodes, doing blight damage and pinning enemies. This blood bomb is made from your own blood.
Acceleration: Reduces cooldowns, but then they are on cooldown for longer when used.
Exchange: Removes debuffs from you then inflicts you with another random debuff.

Version 3.0: Compatible with ToME 1.5.0

This addon supports game play for character levels higher than 50, primarily for the infinite dungeon (I.D.). This implements a number of subtle changes, rescaling game mechanics and balance for character levels above 50 in the Maj'Eyal, Infinite, and Arena campaigns for ToME. The intent is to make it possible (though certainly not easy) to reach level 500 of the Infinite Dungeon. This is not a nerf or a buff to game difficulty per se, but, rather, an extension of the well-balanced game play from the Maj'Eyal campaign to higher levels.

Some talents and status effects have been adjusted to accommodate the higher character levels possible. You can see a summary of these by checking the "Infinite500" tab in Game Options.

Once a character enters the I.D., the level 50 cap is removed and normal stats-per-level progression is enabled from level 51 onward. The limit on how high primary stats may be trained is removed (limited by character level as normal) and dependent computed value limits are also appropriately increased. No additional Prodigies are gained automatically after level 50. (Note that additional category points and (rarely) Prodigies can be gained by completing I.D. challenges.) Talent mastery levels can be improved more than once, and talent levels are unlearnable as normal in the I.D.

NPC levels in the I.D. have been adjusted to be compatible with higher game difficulty settings.

Most monsters and bosses from the Maj'Eyal campaign are imported into the I.D. along with their respective unique drops.

Traps have been added back to the I.D.

Isolated shops can appear randomly in the I.D. There is guaranteed to be at least one shop on level 1, and they become more common for the first few levels, and then more rare with depth.

Random escorts may be randomly generated on each level in the I.D. unless a challenge has been started, until the normal number (9) have been attempted.

The lichform quest is completed in the I.D. with a new random drop instead of automatically being completed at the appropriate step. There is a new greater vault in the I.D. that affects this quest.

The Corruption/Hexes tree can be learned from a new random drop.

Most major events from the Maj'Eyal campaign are enabled in the I.D., and there is a new event that can award the cursed-aura tree.

Undead characters starting in the I.D. begin with an artefact cloak. This is similar to the Cloak of Deception, but its stats scale with character level and it can spawn randomly for other characters.

This addon incorporates some modified game mechanics:
The ability to shrug off critical hits has been changed. Instead of using the percent value to ignore crits completely, it reduces the crit multiplier by the same amount to a minimum of 100%.

Modified checkHit and checkHitOld functions are employed that allow for wider level differences between opponents (see http://forums.te4.org/viewtopic.php?f=36&t=35229).
Saving throws have been modified slightly to make them more effective at reducing the duration of status effects you fail to save against. (See http://forums.te4.org/viewtopic.php?f=36&t=36715 for details.)

Things planned for the future: scaling of world artefacts with character level, map effects with dungeon level.
